YouTube Description Generator

What a YouTube description is actually for
A description has three readers, in this order: YouTube's systems (which read it for topic context), searchers (who see its first lines under your title in results), and the small minority of viewers who expand it looking for links and chapters. The generator structures for all three: topic-rich opening lines for the first two, organized sections and link slots for the third.
The first 100–150 characters do most of the work. They appear in search results as your snippet and above the fold on the watch page — they are, functionally, your ad copy. That's why the generator opens with your topic phrase in a natural sentence rather than a keyword pile: YouTube's systems long ago got smart enough to read stuffing as noise, and human searchers always could.
Chapters: the retention tool disguised as navigation
The chapter scaffold in your generated description isn't decoration. Chapters (timestamps from 0:00) give viewers a map of the video, and counterintuitively, letting people jump ahead tends to help retention rather than hurt it — a viewer who skips to the part they want and watches it fully beats one who scrubs blindly and leaves. Chapters also make your video eligible for enhanced presentation in search. Replace the placeholder timestamps with real ones after your edit locks; YouTube needs the first chapter at 0:00 and at least three chapters to display them.
The links section
Put your most important link early — expanded descriptions get skimmed top-down. If any link is an affiliate link, disclose it plainly right there (“As an affiliate I earn from qualifying purchases”) — it's legally required by the FTC in the US, YouTube expects it, and it reads as honesty rather than apology. Audiences punish hidden commerce far harder than declared commerce.
Frequently asked questions
How long should a YouTube description be?
Long enough to serve its three jobs: 1–2 topic-rich opening sentences (they show in search), chapters if the video runs past a few minutes, and your links with any required disclosures. That's typically 100–250 words. Padding beyond usefulness adds nothing — YouTube reads relevance, not length.
Do YouTube descriptions affect SEO?
Yes — the description is one of the main text signals YouTube uses to understand your video's topic, and its opening lines appear in search results. Natural topic phrases in the first two sentences help; keyword stuffing doesn't and can violate metadata policy. Watch time still outweighs all of it.
How do I add chapters to a YouTube video?
Put timestamps in the description: the first must be 0:00, you need at least three, and each gets a label on its own line (0:00 Intro, 1:24 Setup…). The generator includes the scaffold — replace the placeholders with your real timestamps after editing.
Where should links go in a description?
Most important link first — expanded descriptions get skimmed from the top. Affiliate links need a plain disclosure right where they appear; it's an FTC requirement in the US and it converts better than hiding it, because declared commerce reads as honesty.
How many hashtags should I use?
Up to three meaningful ones — YouTube displays a maximum of three above your title, and more than 60 in a description causes all of them to be ignored. The generator adds three from your topic; edit to taste.
